Abstract
A method of manufacturing an image forming apparatus having an envelope made of members inclusive of a first substrate and a second substrate disposed at a space being set therebetween, image forming means and spacers disposed in the envelope, the spacers maintaining the space, the method comprising the steps of forming a spacer having a desired shape by cutting a spacer base member, and abutting the spacer upon the first and second substrates at non-cut surfaces of the spacer.
Claims5
A method of manufacturing an image forming apparatus, having an envelope made of members inclusive of a first substrate and a second substrate disposed at a space being set therebetween, image forming means and spacers disposed in the envelope, the spacers maintaining the space, the method comprising the steps of:
- forming a groove in a spacer base member and cutting the spacer base member along the groove to form a spacer having a desired shape;
- and
- abutting the spacer upon the first substrate or second substrate at cut surface of the spacer,
- wherein said step of forming a spacer having a desired shape includes a step of forming a conductive film on the groove of the spacer base member, and a step of cutting the spacer base member along the groove to form the spacer having the desired shape.
